New Delhi: Private equity deal tally surged by 30 percent to USD 16 billion through 1,000 deals in 2015, largely driven by the startup segment, which contributed 60 percent of the total investment volume, says a report.

The recent FDI norms and the much awaited GST will perhaps be a game changer and will further accelerate the deal activity from an inbound investment, domestic M&A and PE perspective," Grant Thornton India Partner Prashant Mehra said.
